“…The vapor pressure of mercury at 20°C is 0.16 Pa that corresponds to 14 mg m -3 mercury concentration in air. The solution of SnCl 2 (1%, m/V) was used for the reduction of Hg into elemental form in 0.1 mol L -1 HCl reaction medium [19]. Mercury vapor after volatilization is released out of the solution and carried by an inert gas to The QC/QA of the applied techniques was performed by standard addition method, and it was found that the recovery for the investigated elements ranges for ICP-AES 98.5-101.2%, for ETAAS and CVAAS 96.9-103.2%.…”

The aim of this study was to assess the applicability of the Inductively Coupled Plasma-Atomic Emission Spectrometry (ICP-AES) Electro Thermal Atomic Absorption Spectrometry (ETAAS), and Cold Vapour Atomic Absorption Spectrometry (CVAAS) for the analysis of total content for 23 elements. Deposition and distribution of metals in the air was determined by biomonitoring a widely prevalent moss species from a lead and zinc polluted area of the "Toranica" mine, Republic of Macedonia. Moss species Hypnum cupressiforme, Homalothecium lutescens, Campthotecium lutescens and Brachythecium glareosum were used as very specific and suitable sampling biomonitor. Moss samples were digested by the application of a closed wet digestion using a microwave digestion system. The applied instrumental techniques were useful in order to determine a wider range of content for the analyzed elements; macro contents of Ca, Mg, K and P to trace contents of As, Cd, Co, Ga, and Hg. From data processing the values for Pb and Zn were used as anthropogenic markers. Higher contents of As, Cd and Cu in moss samples from this region were also determined, confirming the impact of mining activities on anthropogenic air pollution in this area. Multivariate factoring identifies four chemical associations: F1 (As-Cd-Ca-Cu-Fe-Mn-Pb-Zn), F2 (Co-Cr-Li-V), F3 (Hg-P) and F4 (K).

“…This limitation can, however, be overcome by the sequential reduction of the two species (inorganic and methylmercury) as proposed by Monteiro et al [119]. Another selective reduction analytical procedure for the determination of inorganic and methylmercury in fish was proposed by Serafimovski et al [127]. Hg measurements were performed by AAS and ICP OES.…”

Abstract.A homogeneity study in the preparation of a fish candidate certified reference material is reported. In the present study, homogeneity was examined by flow injection analysis cold vapour atomic absorption spectrometry technique (FIA-CV-AAS). Total mercury and methylmercury were studied in this study. Univariate analysis of variance (ANOVA) was performed for all analytes. The results were evaluated using an F-test, which demonstrated no significant difference for the between-bottle results. It is indicative that this material is homogeneous. The results of the between-bottle homogeneity study provide for the evaluation of one of the uncertainty components in the certification process.
